This study was undertaken to evaluate safety and antitumor activity of Nexia, a processed extract of Rhus verniciflua STOKES by heating according to Korean patent 0504160 through toxicology, cancer research and clinical application. Nexia did not exhibit any toxicological symptoms through 13 week continuous treatment, dosage accumulation study and anaphylaxis response. The lifespan of four patients with acute lymphocytic leukemia under complete remission were 110, 83, 97, and 86 months after treatment of Nexia, respectively. These data suggest that Nexia, a processed extract by removing allergen from Rhus verniciflua STOKES, may have safety and antitumor activity and also still need continuous study on its mechanism and clinical trial.

Chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS) is a relapsing-remitting disorder for which steroid administration is a key to control the progression. CLIPPERS can exhibit radiological features similar to malignant lymphoma, whose diagnosis is confounded by prior steroid administration. We report a case of CLIPPERS accompanied by abnormal elevation of ${\beta}-2$ microglobulin in the cerebrospinal fluid (CSF). A 62-year-old man started to experience numbness in all fingers of his left hand one year ago, which gradually extended to his body trunk and legs on both sides. Magnetic resonance imaging demonstrated numerous small enhancing spots scattered in his brain and spinal cord. CSF levels of ${\beta}-2$ microglobulin were elevated; although this often indicates central nervous system involvement in leukemia and lymphoma, the lesions were diagnosed as CLIPPERS based on the pathological findings from a biopsy specimen. We emphasize the importance of biopsy to differentiate between CLIPPERS and malignant lymphoma because the temporary radiological response to steroid might be the same in both diseases but the treatment strategies regarding the use of steroid are quite different.

Lymphocytic interstitial pneumonia(LIP) is characterized by a massive infiltration of the interstitium of the lung by mature lymphocytes, plasma cells and reticuloendothelial cells. LIP may be associated with autoimmune diseases including Sj$\check{o}$grens syndrome, SLE, myasthenia gravis, pernicious anemia, autoimmune hemolytic anemia, and HIV or an EB virus infection. There is a possibility of LIP progressing to a pulmonary or systemic lymphoma. The therapeutic response to corticosteroids and/or immunosuppressive drugs varies. Here we report a case of LIP that was diagnosed by an open lung biopsy and clonality study. The patient was a 36 year-old man without autoimmune disease or HIV infection. He was admitted as a result of severe hypoxemia showing $PaO_2$ of 48.3mmHg. The patient was treated with corticosteroids after the diagnosis and had fully recovered without a sequalae or relapse.

Chronic lymphocytic leukemia (CLL)is the most common leukemia in adults in Western countries but is relatively rare in Asia. Immune hemolytic anemia, Evan's syndrome, lymphadenopathy, organomegaly and B symptoms are the main complaints of patients in CLL. The present retrospective analysis evaluated a group of 109 patients with CLL over a 9-year period, studying correlations between sex, age and overall survival. The patients were hospitalized in the Clinic of Hematology and Oncology, Kermanshah, Iran, between 2006 and 2014. Data analysis for sex and age was performed using IBM SPSS19 and overall survival was plotted by Kaplan-Meier plot, Log-rank test in Graph Pad prism 5 Software for five-year periods. The mean age of diagnosis for CLL patients was 60.73 years, 59.6% male. Survival rate patients was 64% and mean overall survival was 38.5 months. In the Rai system, fourteen patients (12.8%) had stage III and twenty eight patients (25.7%) had stage IV. Most frequent clinical features in patients with CLL were lymphadenopathy (38.7%) and organomegaly (34%), respectively. There is not relationship between sex and age in patients but overall survival rate in females was higher than in males. In Asian countries, CLL is more in male and in age above 60 years. Complaints about lymphadenopathy and virus infection are prevalent.

Lymphocytic gastritis (LG) is a rare subtype of chronic gastritis. It is defined as dense proliferation of intraepithelial lymphocytes (IELs) more than 25 lymphocytes per 100 epithelial cells. The known major causes of LG are celiac disease and Helicobacter pylori infection. H. pylori associated LG (HpLG) has more enhanced cytotoxic and apoptotic tendencies than chronic H. pylori gastritis. A 12-year-old girl with postprandial epigastric pain was diagnosed HpLG on endoscopic biopsy. After the 1st eradication therapy, H. pylori bacilli were still found, and urea breathing test was positive. Although the endoscopic finding was partially improved, clinical symptoms and histologic finding were persisted. We could achieve the improvement of clinical symptoms and disappearance of IELs after the 2nd eradication. The discordant of histopathologic and endoscopic improvement occurred after the 1st eradication therapy of HpLG. Therefore the clinical and histopathologic evaluation should be considered as well as endoscopic findings.

Strongyloides stercoralis is a human intestinal parasite which may lead to complicated strongyloidiasis in immunocompromised. Here, a case of complicated strongyloidiasis in a patient with chronic lymphocytic leukemia is reported. Presence of numerous S. stercoralis larvae in feces and sputum confirmed the diagnosis of hyperinfection syndrome in this patient. Following recovery of filariform larvae from agar plate culture of the stool, the isolate was characterized for the ITS1 region of ribosomal DNA gene by nested-PCR and sequencing. Albendazole therapy did not have cure effects; and just at the beginning of taking ivermectin, the patient died. The most important clue to prevent such fatal consequences is early diagnosis and proper treatment.

A 6-year-old, spayed female Miniature Pinscher dog with chronic vomiting lasted for 7 weeks was referred to the Veterinary Medical Teaching Hospital of Chungnam National University. Physical examination, complete blood counts, serum chemistry, gastroscopy, upper gastrointestinal series, endoscopic biopsy and histopathological examination were performed for the diagnosis. The complete blood counts and serum biochemistry revealed no remarkable effect to the patient's general condition. Gastroscopy revealed erosion, erythema in mucosal surface of gastric lesions and endoscopic biopsy performed. No significant findings in upper gastrointestinal series were observed, and histopathologic examination revealed infiltration of lymphocyte in the gastric mucosa. Based on these findings, the dog was diagnosed with lymphocytic gastritis. The dog were treated by metronidazole and ranitidine with hypoallergenic diet, and then the patient showed no vomiting or other complications.

Acute lymphocytic leukemia(ALL) is a malignant disease of the bone marrow in which early lymphoid precursors proliferate and replace the normal hematopoietic cells of the marrow. Currently, only $20-30\%$ of adults with ALL are cured with standard chemotherapy regimens. It is very important risk factor whether to failure to achieve complete remission within 4 weeks or not. The relapse of leukemia is usually classified as hematologic and extramedullary relapse, and extramedullary leukemic infiltration is rarely observed in patients with ALL. In October 2004, a 23-year-old man presented with painless enlargement of both parotid glands. He was diagnosed as ALL(L2 subtype) one month ago, and he gained complete remission with induction chemotherapy. Fine needle aspiration cytology and bone marrow biopsy revealed extramedullary and hemtologic remission. To our knowledge this is the first report of extramedullary relapse in the parotid in ALL.

Although normal thyroid epithelial cells do not constitutively express HLA-DR antigen, their expression in wide spread within thyroid glands obtained from the human with autoimmune thyroid disease and with many neoplastic thyroids. We have, therefore, studied immunohistochemically with regard to the expression of HLA-DR antigen of thyroidectomy specimens from 50 patients of various thyroid diseases with use of paraffin-embedded tissue. One or two sections from each case were stained with commercially available mouse monoclonal antibody for class II HLA-DR antigen(HLA-DR/Alpha, DAKO) and examined by semiquantitative counting system for thyrocytes, neoplastic thyrocytes and other cells expressing HLA-DR antigen. All patients with lymphocytic thyroiditis(2/2) and diffuse hyperplasia(Graves' disease)(5/5), most patients with Hashimoto's disease(9/ll) expressed HLA-DR antigens in thyrocyte with abundant HLA-DR expressing lymphocytic infiltrates with lymph follicle formation in its vicinity or adjacent to the lesion. Most patients with papillary carcinoma(9/1l) had HLA-DR antigen detected in malignant thyrocytes ; while follicular carcinoma(0/3) and follicular adenoma(0/5) did not have detactable HLA-DR immunoreactivity. Adenomatous goiter(3/7) had HLA-DR antigen detected focally in lesser than half cases. Conversely, in four papillary carcinomas and three adenomatous goiters, HLA-DR expression of thyrocytes was found in the absence of HLA-DR expressing lymphoid infiltrates. In such cases therefore other factors more than thyroid autoimmunity must be causative for HLA-DR immunoreactivity. The results of this study indicate as follows. 1) The expression of HLA-DR on thyrocytes involved in autoimmune reactions appeared to be secondary to cytokine release from associated lymphocytic infiltrates. 2) Thyrocytes in thyroid lesions with equal degrees of lymphocytic infiltration without HLA­DR expression exhibited no HLA-DR immunoreactivity. 3) In neoplastic thyrocytes, most papillary carcinoma(9/11) exhibited detactable HLA-DR expression, while follicular carcinoma/adenoma(0/3/0/5) exhibited no detactable HLA-DR immunoreactivity which suggest the existence of divergent mechanisms inducing and modulating HLA-DR expression of different types of neoplastic thyrocytes.
